Infiniti Q50 Hybrid (2018 year). Manual — part 25

The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The main-
tenance schedule indicates at which mile-
age/time intervals each item requires
service.

In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer
to “General maintenance” (P.9-2).

Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You
are not required to perform maintenance on
these items in order to maintain the warran-
ties which come with your vehicle. Other
maintenance items and intervals are re-
quired.

When applicable, additional information can
be found in the “8. Do-it-yourself” section of
this manual.

NOTE:

INFINITI does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on an INFINITI product.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been
validated by INFINITI.

For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to “Capacities
and recommended fluids/lubricants” (P.10-
2) of this manual.

EMISSION CONTROL SYSTEM
MAINTENANCE

Engine air filter:

Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
check/replace the filter more frequently.

Engine coolant*:

Replace coolant at the specified interval.
When adding or replacing coolant, be sure to
use only Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) or equivalent with the
proper mixture. (Refer to “Engine cooling
system” (P.8-5) to determine the proper
mixture for your area.)

NOTE:

Mixing any other type of coolant or the use
of non-distilled water may reduce the
recommended service interval of the cool-
ant.

Hybrid Electronic Vehicle (HEV) inverter
coolant:

Replace inverter coolant at the specified
interval. When adding or replacing coolant,
be sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equivalent

with the proper mixture. (Refer to “Inverter
cooling system” (P.8-7) to determine the
proper mixture for your area.)

NOTE:

Mixing any other type of coolant or the use
of non-distilled water may reduce the
recommended service interval of the cool-
ant.

Engine oil and oil filter:

Replace engine oil and oil filter at the
specified intervals. For recommended oil
grade and viscosity refer to “Capacities and
recommended fluids/lubricants” (P.10-2).

Engine valve clearance*:

Inspect only if valve noise increases. Adjust
valve clearance if necessary.

Evaporative emissions control vapor lines*:

Check vapor lines for leaks or looseness.
Tighten connections or replace parts as
necessary.

Fuel lines*:

Check the fuel hoses, piping and connections
for leaks, looseness, or deterioration. Tight-
en connections or replace parts as necessary.

Spark plugs:

Replace at specified intervals. Install new
plugs of the type as originally equipped.

MAINTENANCE ITEMS

Maintenance and schedules

CHASSIS AND BODY MAINTE-
NANCE

Brake lines and cables:

Visually inspect for proper installation.
Check for chafing, cracks, deterioration,
and signs of leaking. Replace any deterio-
rated or damaged parts immediately.

Brake pads, rotors, drums and linings:

Check for wear, deterioration and fluid
leaks. Replace any deteriorated or damaged
parts immediately.

Exhaust system:

Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deterioration,
and damage. Tighten connections or replace
parts as necessary.

In-cabin microfilter:

Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
replace the filter more frequently.

Propeller shaft(s):

Check for damage, looseness, and grease
leakage. (4WD/AWD/RWD)

Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots:

Check for damage, looseness, and leakage
of oil or grease. Under severe driving condi-
tions, inspect more frequently.

Tire rotation:

Tires should be rotated every 5,000 miles
(8,000 km) according to the instructions
under “Explanation of general maintenance
items” (P.9-2). When rotating tires, check for
damage and uneven wear. Replace if neces-
sary.

Transmission fluid/oil, differential oil and
transfer case oil:

Visually inspect for signs of leakage at
specified intervals.

To help ensure smooth, safe and economical
driving, INFINITI provides two maintenance
schedules that may be used, depending upon
the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 120,000 miles
(192,000 km)/144 months. For most peo-
ple, the odometer reading will indicate when
service is needed. However, if you drive very
little, your vehicle should be serviced at the
regular time intervals shown in the schedule.

After 120,000 miles (192,000 km)/144
months, continue maintenance at the same
mileage/time intervals.

ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
CONDITIONS

Additional maintenance items for severe
operating conditions should be performed
on vehicles that are driven under especially
demanding conditions. Additional mainte-
nance items should be performed if you
primarily operate your vehicle under the
following conditions:
. Repeated short trips of less than 5 miles

(8 km).

. Repeated short trips of less than 10 miles

(16 km) with outside temperatures re-
maining below freezing.

MAINTENANCE SCHEDULES

. Operating in hot weather in stop-and-go

“rush hour” traffic.

. Extensive idling and/or low speed driving

for long distances, such as police, taxi or
door-to-door delivery use.

. Driving in dusty conditions.

. Driving on rough, muddy or salt spread

roads.

. Using a car-top carrier.

NOTE:

For vehicles operated in Canada, both
standard and severe maintenance items
should be performed at every interval.

The following tables show the standard
maintenance schedule. Depending upon
weather and atmospheric conditions, vary-
ing road surfaces, individual driving habits
and vehicle usage, additional or more fre-
quent maintenance may be required.

After 120,000 miles (192,000 km)/144
months, continue maintenance at the same
mileage/time intervals.

NOTE:

(1) If operating mainly in dusty conditions,
more frequent maintenance may be re-
quired.

(2) Periodic maintenance is not required.

(3) First replacement interval is 105,000
miles (168,000 km) or 84 months. After
first replacement, replace every 75,000
miles (120,000 km) or 60 months.

(4) Use only Genuine NISSAN Long Life

Antifreeze/Coolant (blue) or equivalent
with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. Mixing any other type of coolant or
the use of non-distilled water may reduce
the life expectancy of the factory fill cool-
ant.

(5) First replacement interval is 12,5000
miles (200,000 km) or 180 months. After
first replacement, replace every 75,000
miles (120,000 km) or 60 months.

(6) Replace spark plug when the plug gap
exceeds 0.055 in (1.4 mm) even if within
specified replacement mileage.

(7) Periodic maintenance is not required.
However, if valve noise increases, inspect
valve clearance.

“Maintenance under severe driving condi-
tions” (P.9-13).

(1) Periodic maintenance is not required.
